John Stott, Basic Christianity– Details the essential claims of Christianity and the salvation we as Christians claim we both need and can find in Christ; a valuable resource for those exploring Christianity to use alongside reading through one of the Biblical gospel accounts, such as Mark.
Greg Gilbert, What is the Gospel? – Surveys the basics of the Gospel—the good news about how we can be saved due to what Jesus has done through his cross and resurrection; valuable for both outreach as well as gaining personal clarity on the gospel. We recommend at least working through chapters 2-5.
“We believe that election is the eternal purpose of God according to which he effectually regenerates, justifies, sanctifies, and glorifies sinners, not on the basis of anything foreseen in them, but solely based on his free and sovereign grace. We believe that this election comprehends all the means connected with its end such that the salvation of all who trust in Christ is guaranteed, that by God’s unfailing grace all genuine believers will persevere in faith unto full and complete salvation.” – SCC Statement of Faith
